To help you prepare, these CompTIA CySA+ exam objectives clearly outline all the key topics and skills you need to master to pass the exam.

Domain 1: Security Operations

Domain 1: Security Operations

Domain 1 focuses on the core tasks of a cybersecurity analyst, including monitoring system behavior, detecting threats, analyzing logs, using security tools, and improving operational efficiency. It reflects real-world responsibilities in security operations centers (SOCs).

1. System and Network Architecture Concepts

Security analysts must understand how systems and networks are designed and how that design impacts visibility and defense. This includes:

2. Indicators of Malicious Activity

Here focuses on your skills in recognizing suspicious behavior and investigating possible security breaches. Analysts must recognize signs of compromise:

• Network-level indicators: abnormal traffic, beaconing to external servers, unauthorized devices, and port scans.
• Host-level signs: unusual CPU or memory usage, unknown processes, registry changes, or evidence of data exfiltration.
• Application-level indicators: unexpected account creation, service crashes, and suspicious log entries.
• Other signs: phishing emails, social engineering attempts, or obfuscated URLs.

3. Tools and Techniques

This section checks how well you can work with different security tools to find out what’s going on in your environment:

• Packet capture tools (Wireshark, tcpdump) for traffic analysis.
• SIEM and SOAR platforms for log correlation and automation.
• Endpoint detection and response (EDR) for real-time threat monitoring.
• Reputation tools (WHOIS, AbuseIPDB) to check IP/domain histories.
• File analysis using VirusTotal, sandboxing, and hash comparisons.
• User behavior analysis and scripting knowledge (Python, PowerShell, regex) are also important.

4. Threat Intelligence and Threat Hunting

In this section, you are expected to compare threat intelligence and threat hunting, explain how they complement each other, and show how this supports better security outcomes.

• Threat intelligence involves collecting data from open and closed sources to identify and understand attackers. 
• Threat hunting is the proactive search for threats already inside the network, often using IOCs. 

You should also understand how to evaluate confidence levels by checking if the information is timely, relevant, and accurate, so you can decide how to act on it and avoid wasting resources on low-quality intelligence.

5. Operational Efficiency

This part highlights key ways to boost efficiency and streamline processes in security operations, including how to:

• Standardize processes

• • Identify tasks that are repeatable and don’t need human input.
  • Pick tasks that are good candidates for automation.
  • Coordinate your team to set up and manage automation smoothly.

• Streamline operations
  • Use automation and orchestration tools like SOAR.
  • Orchestrate threat intelligence data: enrich it, combine different threat feeds.
  • Reduce manual work to free up your team for higher-level tasks.

• Integrate technology and tools
  • Use APIs, webhooks, and plugins to connect systems.
  • Build a single pane of glass so your team can monitor everything in one place.

Practicing real exam scenarios is the best way to master these core tasks. Try the Security Operations practice test to reinforce what you’ve learned.

Domain 2: Vulnerability Management

Domain 2: Vulnerability Management

As outlined in the CySA+ Exam Objectives, domain 2 is all about how well you can find, assess, and manage vulnerabilities in different systems.

1. Implement Vulnerability Scanning Methods and Concepts

In this section, you will learn about different scanning types, how they work, and how to apply them properly in various environments.

• Asset discovery: Uses map scans and device fingerprinting to identify devices and services.
• Types of scanning:
  • Internal vs. External: Evaluate internal systems vs. internet-exposed assets.
  • Agent vs. Agentless: Agent-based scans offer deeper visibility but require installation.
  • Credentialed vs. Non-credentialed: Credentialed scans provide more accurate system insights.
  • Passive vs. Active: Passive observes traffic; active sends probes to detect vulnerabilities.
  • Static vs. Dynamic: Static reviews source code or binaries; dynamic monitors live behavior.
• Key considerations:
  • Scheduling scans to avoid disruption.
  • Respecting network segmentation, performance limits, and compliance needs.
• Critical infrastructure: Systems like OT, ICS, and SCADA must be scanned cautiously to avoid outages.
• Security frameworks and baselines: Use established standards like CIS Benchmarks, OWASP, PCI DSS, and ISO 27000 to guide scanning scope and depth.

2. Analyze Vulnerability Assessment Tool Output

This section tests your ability to read and interpret scan results, separating valid security concerns from false positives. Here are the tools for vulnerability assessment: 

3. Prioritizing Vulnerabilities Based on Risk

Not all vulnerabilities are equally dangerous; you need to assess and rank them based on risk.

• Use CVSS scores: Evaluate attack vector, complexity, privileges required, user interaction, and impact on CIA.
• Validation: Eliminate false positives and negatives through manual or contextual checks.
• Contextual factors: Consider location (internal vs. external), asset value, and exploit availability (e.g., zero-day threats).

4. Controls to Mitigate Vulnerabilities

You must be able to recommend practical fixes based on the type of security issue identified.

• Examples of vulnerabilities: XSS, injection flaws, buffer overflows, broken access control, and cryptographic failures.
• Mitigation tactics: Input validation, session management, secure coding practices, software patching, and access restrictions.

5. Vulnerability Response and Management

Once vulnerabilities are identified, you must manage the response process from assessment to remediation.

• Types of controls:
  • Preventive: Stop security incidents before they happen (e.g., firewalls, MFA, access controls).
  • Detective: Detect and identify incidents when they occur (e.g., IDS/IPS, log monitoring, audits).
  • Corrective: Fix systems after an incident and prevent it from happening again (e.g., patching, backups, recovery plans).
  • Compensating: Alternative measures when a primary control is not feasible (e.g., extra monitoring when encryption is not possible).
  • Managerial: Policies, procedures, security planning, and risk assessments.
  • Technical: Security technologies like firewalls, endpoint protection, and access management tools.
  • Operational: Day-to-day actions like incident response, user training, and physical security.
• Patch and configuration management: Includes testing, implementation, rollback, and validation within planned maintenance windows.
• Risk management approaches: Risk can be accepted, mitigated, transferred (shifted to a third party, like insurance), or avoided depending on context.
• Governance and escalation: Follow internal policies, document exceptions, and meet service-level objectives (SLOs).
• Attack surface reduction: Use tools like pen testing, bug bounties, and adversary emulation.
• Secure development: Apply secure SDLC, threat modeling, and defensive coding principles to reduce future vulnerabilities.

Domain 3: Incident Response and Management

Domain 3: Incident Response and Management

In domain 3 of the CompTIA CySA+ Objectives, you are expected to understand attack analysis frameworks, respond correctly to various incident scenarios, and perform both preparation and post-incident activities to strengthen your organization’s cybersecurity posture.

1. Attack Methodology Frameworks Concepts

This section tests your understanding of common cybersecurity frameworks used to describe and analyze how cyberattacks happen. These models help cybersecurity professionals identify attacker behavior, understand how threats evolve, and coordinate responses.

• Cyber kill chain: A model that breaks down the stages of an attack from reconnaissance to exfiltration. It helps defenders stop attackers earlier in the process.
• Diamond model of intrusion analysis: Focuses on four core features of an attack (adversary, capability, infrastructure, and victim) and shows how these elements relate to one another.
• MITRE ATT&CK: A matrix of real-world attack tactics and techniques that helps organizations identify what attackers are doing and how to defend against them.
• Open Source Security Testing Methodology Manual (OSSTMM): A guide for performing structured, repeatable security tests across different systems.
• OWASP testing guide: A comprehensive set of best practices for testing web applications for vulnerabilities such as SQL injection and cross-site scripting.

2. Incident Response Activities

This section evaluates your ability to apply incident response steps in a real-world situation. You need to know what to do when a breach occurs, how to collect and protect evidence, and how to restore affected systems.

• Detection and analysis:

• • Indicators of Compromise (IoCs): Signs that an attack may have occurred, such as abnormal traffic or suspicious processes.
  • Evidence acquisition: The process of collecting digital evidence while maintaining the chain of custody, data integrity, and proper preservation for legal or investigative purposes.
  • Data and log analysis: Reviewing system logs and data sources to determine the nature and scope of the incident.
    

• Containment, eradication, and recovery:

• • Scope and impact: Assess how widespread the attack is and which systems are affected.
  • Isolation and remediation: Remove or isolate compromised systems, clean the environment, and fix vulnerabilities.
  • Re-imaging: Restore systems to a clean state using backups or fresh installations.
  • Compensating controls: Temporary security measures used when standard controls are unavailable or insufficient.

3. Preparation and Post-Incident Activity Phases

This section tests your understanding of what should be done before an incident occurs and how to improve systems and processes afterward.

• Preparation:

• • Incident response plan: A documented procedure for identifying, managing, and mitigating incidents.
  • Tools and playbooks: Predefined guides and technologies used to standardize and automate incident handling.
  • Tabletop exercises and training: Practice scenarios and team training to test readiness and improve coordination.
  • Business continuity and Disaster recovery (BC/DR): Plans to keep business operations running or recover quickly during or after a major incident.
    

• Post-Incident activities:

• • Forensic analysis: A detailed technical examination to determine how the incident happened and what data was affected.
  • Root cause analysis: Identifying the underlying issue or failure that allowed the incident to occur.
  • Lessons learned: Reviewing what happened, what worked, what failed, and making improvements to prevent future incidents.
